For the To the frame of the machine proper are atpurpose of creating a blast the fan 21 is protached the side members 7, which side mem-' vided, which fan may be located as illusbers constitute the sides of the elevator-frame trated in the drawings. I00 and to which side members are journaled the Upon the fan shaft 22 are located the roller-shafts 8 and 9, said shafts being located sprocket-Wheels 23, around which sprocketwheels are located the drive-chains 24, said drive-chains leading to and passing around the sprocket-wheels 25,which sprocket-wheels are securely attached to the shaft 26, which shaft is provided with the pinions 2'7. pinions mesh with the wheels 5, thereby communicating rotary motion to the fan 21.

For the purpose of directing the blast of the fan and bringing the same to the rear of the brush the chamber 28 is provided, which chamber is formed of a width to correspond with the length of the brush. It will be understood that as the machine proper is drawn forward rotary motion will be communicated to the brush and to the fan, by which arrangement the dirt lifted by the brush will be blown forward onto the elevator, from whence it is conveyed upward and delivered into the top or upper end of the deliveryspout 29. It will be understood that by the use of the fan and the blast produced thereby the fine particles of dust will be removed from the street, thereby removing all particles from the surface of the street. For the purpose of supporting the front or forward portion of the machine proper the front wheels 30 are provided, which wheels are properly journaled to the bottom or lower ends of the yokes 31 and the top or upper ends of said yokes journaled to the crossbar 32.

For the purpose of providing a means for attaching the sweeper to the rear end of a wagon the hooked bar 33 is provided, which hooked bar is connected to the shaft 34, said Saidment of the levers 16 the side members 14 are provided with the elongated slots 36, through which elongated slots the brushshaft 15 passes.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of a traveling frame, and endless elevator, mechanism therein, a rotating brush adj ustably mounted in the frame at the rear of the elevator mechanism, a fan mechanism mounted on the frame a blastconduit leading from the fan mechanism to the rear of the brush, and means for operating the working parts substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
